Wheeling Suspension Bridge

The Wheeling Suspension Bridge is a suspension bridge spanning the main channel of the Ohio River at Wheeling, West Virginia. It was the largest suspension bridge in the world from 1849 until 1851. Charles Ellet Jr. (who also worked on the Niagara Falls Suspension Bridge) designed it and supervised construction of what became the first bridge to span a major river west of the Appalachian Mountains. It linked the eastern and western section of the National Road, and became especially strategically important during the American Civil War. Litigation in the United States Supreme Court concerning its obstruction of the new high steamboat smokestacks eventually cleared the way for other bridges, especially needed by expanding railroads. Because this bridge was designed during the horse-and-buggy era, 2-ton weight limits and vehicle separation requirements applied in later years until it was closed to automobile traffic in September 2019.

The main span is 1,010 feet (310 m) from tower to tower. The east tower rests on the Wheeling shore, while the west tower is on Wheeling Island. The east tower is 153.5 feet (46.8 m) above the low-water level of the river, or 82 feet (25 m) from the base of the masonry. The west tower is 132.75 feet (40.46 m) above low water, with 69 feet (21 m) of masonry. Detailed analysis of the bridge was conducted by Dr. Emory Kemp.

The Wheeling Suspension Bridge was designated a National Historic Landmark on May 15, 1975. It is located in the Wheeling Island Historic District.

A charter was granted to the Wheeling and Belmont Bridge Company in 1816 to construct a bridge to extend the National Road (also known as the Cumberland Pike because it began in Cumberland, Maryland) across the Ohio River. Although the U.S. Congress authorized the National Road in 1806, and cities competing for that crossing included Wellsburg, West Virginia and Steubenville, Ohio, that bridge connecting Wheeling with Belmont, Ohio was nevertheless completed. The National Road formally reached Wheeling on August 1, 1818, but then ferries took passengers and freight to the other section of the National Road which began in Belmont and continued westward. In 1820 Congress authorized the National Road's extension to St. Louis, Missouri.

Another attempt to charter and construct a bridge across the Ohio River was made more than a decade later. That began in state legislatures and ultimately succeeded in getting the bridge built using new technology. It also produced two rounds of important litigation in the United States Supreme Court, in 1849–1852 and again in 1854–56.

Since 1820 Congress had spent much money to clear navigation obstacles from the Ohio River, which flows from Pittsburgh down through Wheeling (then in Virginia) to Cincinnati, Ohio and eventually reaches the Mississippi River at Cairo, Illinois slightly downstream of St. Louis, Missouri (which became a major inland commercial center). Goods and produce could thus ship fairly cheaply and quickly down the Ohio River and reach the ocean port of New Orleans, Louisiana. Senator Henry Clay of Kentucky had become a great proponent of internal improvements, in part because the Ohio River drained into the northern part of his state and contributed to the growth of Louisville (as did the Louisville and Portland Canal completed in 1830 to bypass the Ohio River's only major rapids). Both road and navigation improvements helped bring manufactured goods and people to Kentucky, western Virginia, Ohio, Indiana, etc., and as well as allowed produce and natural resources to reach eastern, southern and even international markets. However, President Andrew Jackson had a much stingier view of internal improvements than Senator Clay, preferring to leave their construction to private or individual state interests, if at all.

Meanwhile, ferrying the U.S. mail, as well as passengers and goods across the Ohio river at Wheeling to connect the two sections of the National Road proved cumbersome and expensive. Maintaining the (initially free) National Road also cost money, especially after floods in 1832 left debris, as well as destroyed shore facilities. In 1835 Congress (dominated by Jacksonian Democrats) gave existing sections to the adjoining states, in order to pass on those maintenance costs. In the interim, new steamboat technology helped goods move upstream as well as downstream, and both railroad and bridge technology had also evolved. Nonetheless, navigation on the Ohio River between Wheeling and Pittsburgh remained hazardous at certain times of year (because of ice and debris in winter and spring floods, as well as summer low water).

Pittsburgh and Wheeling both competed to become commercial hubs connecting east and west across the central Appalachian Mountains. To the north, the Erie Canal (completed 1825 between Buffalo, New York on Lake Erie and Albany, New York on the Hudson River) and the Welland Canal (completed 1829 connecting Lake Erie and Lake Ontario bypassing Niagara Falls and creating the St. Lawrence Seaway) proved a commercial boon even to cities some distance away (especially New York City as a seaport, but also Erie, Pennsylvania). Soon, Pennsylvania competed by subsidizing first a short canal ending at Pittsburgh, then railroads connecting Pittsburgh to Philadelphia, which had rail and water connections to New York City and was a major international port in its own right. In 1835, a new incline railroad connected Pittsburgh to Ohio valley produce and goods. The combination of Pennsylvania railroads and canals became known as the "Main Line". In 1846 Pennsylvania's legislature chartered the Pennsylvania Railroad to connect its state capital Harrisburg (which had many connections to Philadelphia) with Pittsburgh. While transappalachian commerce initially boomed in part because canals enabled one man, one boy, a horse and a boat to transport what had previously involved ten men, ten wagons and sixty horses (and the Pennsylvania route was shorter route for most Ohio valley goods and produce than the New York routes), toll revenues proved insufficient. Since 1844 Pennsylvania had been trying to sell its unprofitable investment.
